Azimuth thruster for ships : L-drive
(with twin counter-rotating propellers) SCHOTTEL

In contrast to pod drives with an electric motor inside the underwater pod, the motor in the new propulsion system will be integrated vertically into the support tube of the Rudderpropeller. This arrangement of the electric motor means that the concept is similar to that of a Rudderpropeller with a vertical power input (“L system”). Moreover, neither an above-water gearbox nor a cardan shaft will be required, making the system extremely compact and easy for the shipyard to install in the vessel.
